Like Gears of Wars’ Beast Mode or L4D2’s versus mode, Resident Evil 6’s Agent Hunt mode lets you play as the zombies and other enemies from RE6 as you kill a bunch of humans. You can watch some gameplay footage after the break.

Looks pretty cool to me. Depends on how it’s done.
Apparently it’s like Dark Souls (or Mindjack, haha) and you can ‘invade’ other players’ games, but only once they’ve completed the game at least once. I guess it’ll give that extra bit of challenge if you wanna replay it.
